A transgenic vector was generated to include the endothelial-specific receptor tyrosine kinase (Tek) driving vascular endothelial specific expression of beta-1,4-N-acetyl-galactosaminyl transferase 2 (B4galnt2), followed by a simian virus 40 intron and a polyadenylation signal (polyA). This transgene is lacking 23 bp of B4galnt2 3'UTR for detection purposes. Line 1108 was established. (J:52069)
